I was bored, so I compiled a list of 77 of my favorite open-source privacy-focused software. This ranges from Android apps to desktop apps to websites to operating systems. I scraped the programming languages used for each one from their respective repositories, and created a simple scoring system to score each programming language.

Obviously there is some bias, since Kotlin is very popular for Android apps and not much else, and it’s not an exhaustive list, so some data might be off, but it was still fun to make! Just wanted to share it with all of you, in case anyone else finds it interesting.

    • The 8232 ProjectOP

      Rust is ranked #26 with a score of 351. The only program that used it at all was Mullvad VPN. It was used as the majority language for that program, amounting to 35.1% of the entire program.

        It was more of a joking question 😅 It’s a shame that such a good, lightweight and secure programming language is not used. It’s not even in the top 20 😔

        • @WhatAmLemmyEnglish
          10•3 months ago

          If you only included projects created in the last 2 or 5 years rust would be ahead of C/C++, possibly ahead of all other strongly typed langs. Kotlin is usually chosen explicitly for modern Android and Java lib interoperability.

          I would be willing to wager that within the next 1-2 decades, LLM transpilation will be used to replace most C/C++ code, too. LLM’s can’t be trusted to write code, but they can be trusted to transpile in combination with TDD. If a codebase is already well tested then transpilation is many orders of magnitude easier.
